Sand Casting For Manufacture Manufacturing ProcessPattern casting Wikipedia
Mold Setup For Sand Casting The setup of a sand mold in manufacturing involves using a pattern to create an impression of the part to be sand cast within the mold removal of the pattern the placement of cores if needed and the creation of a gating system within the mold The setup of a mold is covered in detail in metal casting processWhen the pattern is to be removed from the sand mold there is a possibility that any leading edges may break off or get damaged in the process To avoid this a taper is provided on the pattern so as to facilitate easy removal of the pattern from the mold and hence reduce damage to edg
